Dynamat Mobile Xtreme Door Kit - 10435

Don't Buy Half A Sound System

Why does your car stereo sound louder when you pull off the freeway and come to a stop? Road noise steals much of the listenable portion of your music. At 70 mph, a typical automotive noise level of 85 dB leaves you with only 20 dB of listenable music. Applying Dynamat creates a "sonic barrier" restoring 3, 6, even 12 dB of lost dynamic range. Gaining just 3 dB doubles your effective amplifier power. And that means you hear more music.

Dynamat Door Kits come in two levels of performance. The Original Door Kit offers the best value for the money. The Xtreme Door Kit controls vibration four times better than Dynamat Original and requires no heat for installation, which makes the Dynamat Xtreme Door Kits a great choice for do-it-yourselfers.

Xtreme Door Kit

Kit contains four 12" x 36" (305mm x 914mm) pieces of Dynamat Xtreme to reduce road noise so you Hear More Music!™. Kit includes enough material for two standard size doors. For proper installation, use one of our Dynaroller tools.

Kit Contains: Material for two vehicle doors full coverage*

Contents: (4) 12" x 36" (305mm x 914mm) pieces of Dynamat Xtreme

Application: Use to hear more music from speakers installed in doors and to reduce road noise.

* Door vary is size from vehicle to vehicle. The Dynamat Original Door Kit contains enough material for two average sized car doors.

Stop fighting engine rumble, speaker rattle, road noise and buzzing vehicle parts! Apply Dynamat Xtreme to your vehicle's resonant surfaces and enjoy improved clarity, loudness and bass response from your car stereo. High-performance Dynamat Xtreme is lighter than Dynamat Original, four times more effective, requires no heat to apply and is recommended for vehicle tops, sides and contoured areas. Dynamat Xtreme is coated with aluminum for high temperature areas such as firewalls and floors. Depending on your needs, choose Dynamat Xtreme in either application-specific kits (pre-cut material in appropriately-sized pieces) or in sheets you can cut to fit.

Description

Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum constrained-layer vibrational damper. Dynamat Xtreme conforms and fuses easily to sheet metal and other hard substrates. Material performance is optimized for temperature ranges between 14°F and 140°F (-10°C to +60°C). Material can withstand temperature extremes between -65°F and +300°F (-54°C to +149°C) and is highly resistant to aging.

Acoustic Properties
The acoustic loss factor "n" is used as a measure of a material's ability to damp structure-borne sound by stating how much vibrational energy (in steel sheets for instance) is converted to heat rather than sound. For constructions containing several layers of damping material, the combined loss factor "n comb" is used. The theoretical maximum loss factor is 1 (no vibration). An undamped 1mm thick steel panel has a loss factor of roughly 0.001 at 200 Hz. Dynamat Xtreme applied to that panel would increase the loss factor to 0.417 @ +20°C (+68°F). Multiple layers of Dynamat Xtreme improve sound damping even more.

Applications
Dynamat Xtreme can be die cut to shape and placed onto the body surface directly on painted panels or after the sheet metal is cleaned before painting (typically at the sealer application operation). Dynamat Xtreme is used to treat metal panels, partitions, ducts, doors, bins, panels, and so forth in railroad cars, buses, automobiles, and ships. It is also used for ventilation ducts, relay cabinets, steel furniture, home appliances, sink units, computer equipment, machine tools and many other objects that suffer from vibration-produced noise.

Installation
Use scissors, knife or die to cut Dynamat Xtreme to the desired size and shape before removing the release liner. Next, remove dust, grease, moisture, and other foreign matter from the application surface. Peel off the release liner. The simplest application technique is to bend the mat slightly and attach it along its shortest edge. Press the mat firmly into place, using a roller for larger pieces. The roller reduces the risk of leaving air pockets, which reduce Dynamat's sound damping capacity. The temperature of the mat and application surface should not be below room temperature during fitting. Heating the material is not necessary.
